[Objective] This article mainly discussed the potential of myocardial cellregeneration and the possible mechanisms involved. [Method] To study the mechanism of cardiac regeneration ability HSCs, this review studyed the relationship of the differentiation of cardiac stem cells, hematopoietic stem cells, myocardial cells and myocardial regeneration and the possible mechanisms involved. [Result] Self-renewing, differentiation both in vitro and in vivo of the c-kit positive CSCs had been seen. No matter in physiological condition or after damage, the c-kit positive CSCs had clonality and the potential of multi-directional differentiation. Hematopoietic stem cells can generate cardiomyocytes and coronary blood vessels for human celltherapy. The ability of dedifferentiation cells to maintain and improve the ventricular function of a damaged heart is very limited. [Conclusion] CSCs and HSCs play an important role in reversing chronic ischemic and non-ischemic heart failure.

Henoch-Sch(o)nlein purpura(HSP) is one of the most common vasculitides in children with many manifestations including skin purpura,arthritis,abdominal pain and renal involvement.The renal involvement(Henoch-Sch(o)nlein purpura nephritis,HSPN) is the principal cause of morbidity and major risk factor for prognosis in HSP.The paper reviewed the updated treatment strategy for HSPN.Accordingly,steroids,cyclophosphamide,mycophenolate mofetil,mizoribine,cyclosporine,triptolide,angiotensin converting enzyme inhibitors (ACEI) / angiotensin receptor blockers(ARB),plasma apheresis and tonsillectomy are possible indicator for the further therapy of HSPN.Furthermore,prospective randomized controlled treatment studies on children with severe HSPN would be needed.

The early treatment principles of spinal cord injury (SCI) included early drug using, early surgery and early rehabilitation.The literatures on how to use drug early and how to control the time for SCI before surgery were reviewed.

Objective To investigated the neuroprotective effect of PTEN inhibitor BPV on cerebral ischemia-reperfusion injury in rats and its mechanism. Methods Male Sprague-Dawley rats were used to induce a reperfusion model of middle cerebral artery occlusion for 1 h. During the reperfusion, the BPV solution (0. 2 mg/kg daily) or the equal volume of saline was injected intraperitonealy immediately. The neurological deficit scores were conducted at day 1, 3,5, and 7 after ischemia-reperfusion. At day 4, triphenyl tetrazolium chloride staining was used to assess cerebral infarction volume. Enzyme-linked immunosorbent assay was used to detect the levels of interleukin 10 (IL-10) and tumor necrosis factor α(TNF-α) in cortical ischemic border zones. Real-time quantitative polymerase chain reaction was used to detect the expression level of PTEN mRNA. Western blotting was used to detect the expression levels of PI3K, Akt, and p-GSK-3β. At day 7, Bielschowsky silver staining was used to detect the axonal distribution in the ischemic border zone of the striatum. Immunohistochemical staining was used to detect the expression of myelin basic protein (MBP). Results At day 4 after ischemia-reperfusion, the infarct volume (32. 27% ± 1. 71% vs. 45. 49% ± 2. 12% ; P < 0. 001), TNF-α concentration in the cortical ischemic border zones (134. 17 ± 10. 38 pg/ml vs. 264. 17 ± 24. 84 pg/ml; P < ), and PTEN mRNA level (1. 19 ± 0. 08 vs. 2. 50 ± 0. 06; P < 0. 001) in the rats of the BPV group were al significantly lower than those of the normal saline group. The IL-10 concentration (186. 83 ± 10. 83 pg/ml vs. 147. 83 ± 11. 62 pg/ml; P < 0. 001), and the expression levels of PI3K (0. 43 ± 0. 08 vs. 0. 26 ± 0. 06; P = 0. 004), Akt (0. 52 ± 0. 05 vs. 0. 40 ± 0. 04;P = 0. 001), and p-GSK-3β (0. 75 ± 0. 08 vs. 0. 38 ± 0. 06; P < 0. 001) were al significantly higher than those of the normal saline group. At day 7 after ischemia-reperfusion, the neurological deficit score (4. 83 ± 0. 41 vs. 6. 33 ± 0. 52; P < 0. 001) in the rats of the BPV group was significantly lower than that of the normal saline group. The axon densities in the ischemic border zones (35. 51% ± 2. 45% vs. 25. 31% ± 2. 79% ; P < 0. 001) and the expression level of MBP (32. 56% ± 3. 46% vs. 27. 81% ± 4. 18% ; P = 0. 037) were significantly higher than those of the normal saline group. Conclusions BPV has neuroprotective effect for cerebral ischemia-reperfusion injury in rats. Its mechanism may be associated with the up-regulation of PTEN downstream proteins PI3K, Akt and p-GSK-3β expression to regulate inflammatory mediators and reduce the inflammatory response.

Nicotinamide and Exendin-4 could promote transdifferentiation of rat BM-MSCs into insulin-producing cells in vitro, which expressed insulin, C-peptide and related genes.

Objective To explore clinical results of posterior spinal approach microendoscopic disectomy(MED) for the treatment of lumbar disc herniation in adolescents.Methods A total of 25 consecutive patients treated by MED from February 2000 to August 2004 in this hospital were analyzed retrospectively.Clinical results were assessed with the modified Macnab criterion.Pre-and post-operative symptoms and functional states were evaluated by the Chinese version Oswestry Disability Index(ODI).Results A conversion to open procedure was required in 1 patient.The operating time was 35～65 minutes(mean,44.8?9.0 minutes);the estimated blood loss during operation was 30～80 ml(mean,51.3?14.6 ml);the postoperative hospital stay was 6～10 days(mean,7.5?1.0 days).All incisions healed by first intention.There were no dural tears,nerve root injuries,intervertebral space infections,or great vessel injuries.Twentg-two patients were followed for 7～57 months(mean,33.4?17.8 months).There were significant differences between preoperative ODI(46.2%?8.5%) and postoperative ODI(1.8%?3.0%).The improvement rate of ODI was 44.4%?9.2%(t=21.61,P=0.00).Clinical results assessment by the modified Macnab criterion revealed "excellent" in 19 patients and "good" in 3 patients,the rate of excellent or good results being 100%. Conclusions Microendoscopic disectomy can be performed safely and effectively for lumbar disc herniation in adolescents,resulting in little trauma,fast recovery,and excellent clinical results.

Objective To evaluate the safety and possibility of coronary intervention in uremic patients on dialysis. Methods Three uremic patients with unstable angina pectoris were treated successfully with percutaneous transluminal coronary angioplasty and stenting. In order to minimize the adverse effect on kidney due to contrast, non-ionic and low osmolar contrast medium was used and coronary angiography and intervention therapy were performed separately. Further protection of the renal function was effected by more frequent dialysis and increasing fluid administration. Results Coronary contrary shows the stenosis of multiple vessels in one patient, unique vessel lesion in two patients. One to four stents were placed. Clinical follow-up period of 12-18 months after procedure, angina pectoris disappeared in all three patients and no deterioration of renal function was noted. Conclusion It is possible to perform coronary angiography and stenting in uremic patients on hemodialysis successfully and safely, provided due attention was paid to the choice of contrast medium and protective measures for renal function.
